N. Carleton M.A. Abstract Background: Differences in attentional processes have been linked to the development and maintenance of psychopathology. Shifts in such processes have been described by the constructs Dissociation and Absorption. Dissociation occurs when external and/or internal stimuli are excluded from consciousness due to discrepant, rather than unitary, manifestations of cognitive awareness [Erdelyi MH. 1994: Int J Clin Exp Hypnosis 42:379,390]. In contrast, absorption can be conceptualized by a focus on limited stimuli, to the exclusion of other stimuli, because of unifying, rather than discrepant, manifestations of cognitive awareness. The Dissociative Experiences Scale [DES; Bernstein EM, Putnam FW. 1986: J Nerv Ment Dis 174:727,735] and Tellegen Absorption Scale [TAS; Tellegen A, Atkinson G. 1974: J Abnorm Psychol 83:268,277] are common measures of each construct; however, no factor analyses are available for the TAS and despite accepted overlap, no one has assessed the DES and TAS items simultaneously. Previous research suggests the constructs and factor structures need clarification, possibly including more parsimonious item inclusion [Lyons LC, Crawford HJ. 1997: Person Individ Diff 23:1071,1084]. The purpose of this study was to evaluate the factor structure of the DES and TAS and create a psychometrically stable measure of Dissociation and Absorption. Methods: This study included data from an undergraduate (n=841; 76% women) and a community sample (n=233; 86% women) who each completed the DES and TAS. Results: Exploratory factor analyses [Osborne JW (ed). 2008: Best Practices in Quantitative Methods. Los Angeles: Sage Publications Inc.] with all DES and TAS items suggested a 15-item 3-factor solution (i.e., imaginative involvement, dissociative amnesia, attentional dissociation). Confirmatory factor analyses resulted in excellent fit indices for the same solution. Conclusions: The items and factors were conceptualized in line with precedent research as the Attentional Resource Allocation Scale (ARAS). Comprehensive results, implications, and future research directions are discussed. Depression and Anxiety, 2010. © 2010 Wiley-Liss, Inc. [source] Placing Progress: Contextual Inequality and Immigrant Incorporation in the United StatesECONOMIC GEOGRAPHY, Issue 3 2008Jamie Goodwin-White Abstract This article contributes to the growing body of research on the economic incorporation of immigrants by considering the relative wages of immigrants, the adult children of immigrants, and the U.S.-born children of U.S. parentage. By disaggregating these three groups racially, comparing entire wage distributions, and comparing the immigrant cities of New York and Los Angeles with the United States overall, it presents a perspective on the complicated contexts of the intergenerational progress of immigrants. In addition to comparing the groups' relative positions in 1990 and 2000, the article decomposes relative wages such that differences in the educational composition of groups can be isolated from residual wage inequality. This research is of interest because consideration of the U.S.-born or educated children of immigrants invokes questions of social mobility and the persistence of ethnic inequality more generally. The article also contributes to a theoretical debate over place and immigrants' progress by examining the second generation, for whom residence in immigrant cities is often theorized as detrimental to economic incorporation. Finally, it introduces a substantial analysis of local wage structures to questions of immigrants' intergenerational economic progress to a much greater extent than has previously been the case. The results suggest that prospects for immigrants' economic incorporation are geographically specific and should be assessed across multiple generations as a result of the continuing contexts of racial wage inequality [source] Geography and the Immigrant Division of LaborECONOMIC GEOGRAPHY, Issue 3 2007Mark Ellis Abstract: Immigrants concentrate in particular lines of work. Most investigations of such employment niching have accented either the demand for labor in a limited set of mostly low-wage industries or the efficiency of immigrant networks in supplying that labor; space has taken a backseat or has been ignored. In contrast, this article's account of immigrant employment niching modulates insights built on social network theories with understandings derived from relative location. We do so by altering the thinking about employment niches as being metropolitan wide to considering them as local phenomena. Specifically, the analysis examines the intraurban variation in niching by Mexican, Salvadoran, Chinese, and Vietnamese men and women in four industries in Los Angeles. Niching is uneven; in some parts of the metropolitan area, these groups niche at high rates in these industries, whereas in others, there is no unusual concentration. We show how a group's propensity to niche in an industry is generally higher when the industry is located close to the group's residential neighborhoods and demonstrate the ways in which the proximity of competing groups dampens this geographic advantage. The study speaks to debates on immigrant niching and connects with research on minority access to employment and accounts of the agglomeration of firms. More generally, it links the geographies of home and work in a new way, relating patterns of immigrant residential segregation to those of immigrant employment niches. [source] Assessment and surgical outcomes for mild type I and severe type II cortical dysplasia: A critical review and the UCLA experienceEPILEPSIA, Issue 6 2009Jason T. Lerner Summary Recent findings on the clinical, electroencephalography (EEG), neuroimaging, and surgical outcomes are reviewed comparing patients with Palmini type I (mild) and type II (severe) cortical dysplasia. Resources include peer-reviewed studies on surgically treated patients and a subanalysis of the 2004 International League Against Epilepsy (ILAE) Survey of Pediatric Epilepsy Surgery. These sources were supplemented with data from University of California, Los Angeles (UCLA). Cortical dysplasia is the most frequent histopathologic substrate in children, and the second most common etiology in adult epilepsy surgery patients. Cortical dysplasia patients present with seizures at an earlier age than other surgically treated etiologies, and 33,50% have nonlocalized scalp EEG and normal magnetic resonance imaging (MRI) scans. 2-(18F)Fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) is positive in 75,90% of cases. After complete resection, 80% of patients are seizure free compared with 20% with incomplete resections. Compared with type I, patients with type II cortical dysplasia present at younger ages, have higher seizure frequencies, and are extratemporal. Type I dysplasia is found more often in adult patients in the temporal lobe and is often MRI negative. These findings identify characteristics of patients with mild and severe cortical dysplasia that define surgically treated epilepsy syndromes. The authors discuss future challenges to identifying and treating medically refractory epilepsy patients with cortical dysplasia. [source] Cocaine Rapid Efficacy Screening Trial (CREST): a paradigm for the controlled evaluation of candidate medications for cocaine dependenceADDICTION, Issue 2005Deborah B. Leiderman ABSTRACT Aim Development of effective medications for the treatment of cocaine dependence remains a major priority for the National Institute on Drug Abuse (NIDA) at the National Institutes of Health. The Cocaine Rapid Efficacy Screening Trial (CREST) paradigm was developed by the Division of Treatment Research and Development (DT R&D) at NIDA with the goal of enhancing pilot clinical trial validity when systematically assessing a range of medications and drug classes for potential utility in treatment of cocaine dependence. Design CREST utilizes a randomized, controlled, parallel group, blinded methodology for comparing one or more marketed medications against a standard, pharmaceutical grade placebo. The trial design is comprised of a flexible 2,4-week screening/baseline period followed by randomization to an 8-week treatment period. Measures Standard measures of outcomes for the CREST included urinary benzoylecgonine (primary metabolite of cocaine), retention, cocaine craving, depression, clinical global impression and HIV-risk behaviors. In order to facilitate comparisons of data from the CREST studies across sites, drug classes and time, standardized procedures, measures and psychosocial counseling were used. Results A total of 19 medications were evaluated in out-patient treatment research clinics in Boston, Cincinnati, Los Angeles, New York and Philadelphia. Conclusions Findings supported decisions to move forward three medications (cabergoline, reserpine, tiagabine) using full-scale, adequately powered, randomized placebo-controlled trial designs. Lessons learned from the CREST experience continue to shape cocaine pharmacotherapy trial design and execution. [source] Discourses on Family Time: The Cultural Interpretation of Family Togetherness in Los Angeles and RomeETHOS, Issue 3 2008Tamar Kremer-Sadlik Analysis indicates that in Los Angeles, California, parents talk about sheltering and isolating their nuclear family from the outside world and from everyday routine by creating special times and special activities for the nuclear family. In contrast, Roman parents' discourse allows for spontaneous times with the family that are diffused within routines and merged with other community members, institutions, and social spaces. We argue that differences displayed in parents' discourses are shaped by culturally specific orientations toward time, family, and individual versus shared responsibility. Through this cross-cultural comparison we contribute to the understanding of how local cultural models shape different ways in which parents interpret time spent in family and influence individuals' perceptions of their everyday lives.

[source] Globalizing Disaster Trauma: Psychiatry, Science, and Culture after the Kobe EarthquakeETHOS, Issue 2 2000Joshua Breslau In January of 1995 a massive earthquake struck the city of Kobe, Japan. This article examines how this event became an opportunity for extending global networks of the science and medicine of trauma. The article is based on ethnographic research in Kobe and Los Angeles with psychiatrists who responded to the earthquake in its immediate aftermath. Three aspects of the process are examined: 1) changes in psychiatric institutions that were ongoing at the time of the earthquake, 2) the place of psychiatry in Japanese cultural self-criticism, and 3) the particular technologies for identifying and treating trauma. Globalization in this case cannot be seen as an imposition of Western cultural forms, but rather an ongoing process that reproduces differences between cultures as particular elements travel between them. [source] Disability payments, drug use and representative payees: an analysis of the relationshipsADDICTION, Issue 7 2003James A. Swartz ABSTRACT Aims This study attempted to determine: if US federal cash disability payments increase the use of cocaine or opiates among those requalifying for supplemental security income (SSI) disability benefits compared with those who lost benefits; if drug use peaks at the beginning of the month after the receipt of the disability cash disbursement; and if money management by representative payees of requalifying SSI recipients suppresses drug use. Design A multi-site, prospective, 2 year longitudinal design was used with follow-up interviews conducted every 6 months. Urine samples were collected at the final three follow-up interviews. Setting Data were collected in Chicago, IL, Los Angeles, CA, and Seattle, WA, USA. Participants This study used a randomly selected sample of 740 former recipients of SSI who had received disability benefits for drug addiction and alcoholism (DA&A) in 1996, were between the ages of 21 and 59 years, had not received concurrent social security disability insurance and provided testable urine samples and complete self-report data for at least one follow-up interview. Measurements Independent variables included demographics, SSI status at follow-up, representative payee status, drug treatment participation and income. Time of drug testing was operationalized as the first 10 days of the month versus the last 20,21 days based on when the urine sample was collected. The dependent variables were cocaine and opiate use, determined by urinalysis results. Findings Participants were 28% more likely to test positive for cocaine use in the first 10 days of the month than later in the month. This effect was general across all subjects and was not restricted to those receiving SSI benefits. No such effect was found for opiate use. Receiving SSI benefits did not increase cocaine or opiate use generally, nor did having a representative payee suppress use. Conclusions The findings do not support the contentions that federal cash benefits appreciably increase drug use or that representative payees discourage use, at least when use is defined dichotomously. The ,check effect' for cocaine use appears to be general and not confined to those receiving federal cash benefits. The lack of a ,check effect' for opiate use is probably the result of the difference between a relatively steady state of opiate use associated with addiction and a binge pattern of cocaine use triggered by suddenly flush resources. [source] What Do Teens Want to Know About Money,A Comparison of 1998 and 2008FAMILY & CONSUMER SCIENCES RESEARCH JOURNAL, Issue 4 2010Karen P. Varcoe Research indicates that the financial literacy of U.S. teens is low, yet they have access to and spend a great deal of money each year. Teens were surveyed in 1998 (N = 323) and again in 2008 (N = 558) to determine what teens wanted to know about money and how they wanted to learn. Data were collected regarding teens' sources of income, why money was important, the types of financial information they would like to learn, and how they would like to learn from seven counties in California,Alameda, Kern, Los Angeles, Riverside, San Diego, San Luis Obispo, and Santa Barbara. The findings indicate that teens are still interested in learning about many of the same financial topics identified in 1998, but their desire for web education has increased. These data can be used to develop programs that will interest teens. [source] Regrounding the ,Ungrounded Empires':localization as the geographical catalyst for transnationalismGLOBAL NETWORKS, Issue 2 2001Yu Zhou The emerging literature on transnationalism has reshaped the study of immigration in the USA from ,melting pot' and later ,salad bowl', to ,switching board', which emphasizes the ability of migrants to forge and maintain ties to their home countries. Often under the heading of ,transnationalism from below', these studies highlight an alternative form of globalization, in which migrants act as active agents to initiate and structure global interactions. The role of geography, and in particular, localization in transnational spaces, is central to the transnationalism debate, but is yet to be well articulated. While it has been commonly claimed that transnationalism represents deterritorialized practices and organizations, we argue that it is in fact rooted in the territorial division of labour and local community networks in immigrant sending and receiving countries. We examine closely two business sectors engaged in by the Chinese immigrants in Los Angeles: high-tech firms and accounting firms. Each illustrates, respectively, the close ties of Chinese transnational activities with the economic base of the Los Angeles region, and the contribution of local-based, low-wage, small ethnic businesses to the transnational practices. We conclude that deeper localization is the geographical catalyst for transnational networks and practices. [source] The State-by-State Economic Impacts of the 2002 Shutdown of the Los Angeles,Long Beach PortsGROWTH AND CHANGE, Issue 4 2008JIYOUNG PARK ABSTRACT In previous research, the economic impacts of temporary shutdowns of the Los Angeles,Long Beach harbors were simulated after a hypothetical terrorist attack, applying the National Interstate Economic Model to estimate state-by-state as well as interindustry impacts. However, the unpredictable characteristic of terrorist attacks might not be applicable to the case of a ports shutdown such as the one caused by the lockout of September,October 2002. Market participants can be expected to have contingency plans based on anticipations of a strike or shutdown. Can we identify any of these in terms of the use of alternate ports, in terms of alternate modes or even alternate time periods? The purpose of this study is to examine these questions. The approach is elaborated by testing for the possible effects of trade diversion to other West Coast ports, transportation modes, and intertemporal substitutions. We use data from WISERTrade describing commodity-specific trade for the major West Coast ports before, during, and after the 11-day shutdown of the fall of 2002. Shippers' ability to divert trade is a key ingredient in the economy's ability to withstand attacks and disruptions. The work estimates the impacts on 47 industrial sectors across 50 states (and the District of Columbia). [source] Preventive HIV Vaccine Acceptability and Behavioral Risk Compensation among a Random Sample of High-Risk Adults in Los Angeles (LA VOICES)HEALTH SERVICES RESEARCH, Issue 6 2009Peter A. Newman Objective. To assess HIV vaccine acceptability among high-risk adults in Los Angeles. Study Setting. Sexually transmitted disease clinics, needle/syringe exchange programs, Latino community health/HIV prevention programs. Study Design. Cross-sectional survey using conjoint analysis. Participants were randomly selected using three-stage probability sampling. Data Collection. Sixty-minute structured interviews. Participants rated acceptability of eight hypothetical vaccines, each with seven dichotomous attributes, and reported post-vaccination risk behavior intentions. Principal Findings. Participants (n=1164; 55.7 percent male, 82.4 percent ethnic minority, mean age=37.4 years) rated HIV vaccine acceptability from 28.4 to 88.6; mean=54.5 (SD=18.8; 100-point scale). Efficacy had the greatest impact on acceptability, followed by side effects and out-of-pocket cost. Ten percent would decrease condom use after vaccination. Conclusions. Findings support development of social marketing interventions to increase acceptability of "partial efficacy" vaccines, behavioral interventions to mitigate risk compensation, and targeted cost subsidies. [source] Patterning and Templating for NanoelectronicsADVANCED MATERIALS, Issue 6 2010Kosmas Galatsis Abstract The semiconductor industry will soon be launching 32,nm complementary metal oxide semiconductor (CMOS) technology node using 193,nm lithography patterning technology to fabricate microprocessors with more than 2 billion transistors. To ensure the survival of Moore's law, alternative patterning techniques that offer advantages beyond conventional top-down patterning are aggressively being explored. It is evident that most alternative patterning techniques may not offer compelling advantages to succeed conventional top-down lithography for silicon integrated circuits, but alternative approaches may well indeed offer functional advantages in realising next-generation information processing nanoarchitectures such as those based on cellular, bioinsipired, magnetic dot logic, and crossbar schemes. This paper highlights and evaluates some patterning methods from the Center on Functional Engineered Nano Architectonics in Los Angeles and discusses key benchmarking criteria with respect to CMOS scaling.

Zedler Impacts of climate change on US wetlands will add to those of historical impacts due to other causes. In the US, wetland losses and degradation result from drainage for agriculture, filling for urbanization and road construction. States that rely heavily on agriculture (California, Iowa, Illinois, Missouri, Ohio, Indiana) have lost over 80% of their historical area of wetlands, and large cities, such as Los Angeles and New York City, have retained only tiny remnants of wetlands, all of which are highly disturbed. The cumulative effects of historical and future degradation will be difficult to abate. A recent review of mitigation efforts in the US shows a net loss of wetland area and function, even though ,no net loss' is the national policy and compensatory measures are mandatory. US policy does not include mitigation of losses due to climate change. Extrapolating from the regulatory experience, one can expect additional losses in wetland areas and in highly valued functions. Coastal wetlands will be hardest hit due to sea-level rise. As wetlands are increasingly inundated, both quantity and quality will decline. Recognition of historical, current and future losses of wetland invokes the precautionary principal: avoid all deliberate loss of coastal wetland area in order to reduce overall net loss. Failing that, our ability to restore and sustain wetlands must be improved substantially. [source] Semen quality in fertile US men in relation to geographical area and pesticide exposureINTERNATIONAL JOURNAL OF ANDROLOGY, Issue 1 2006Shanna H. Swan Summary We conducted the first US study to compare semen quality among study centres using standardized methods and strict quality control. We present data on semen quality in partners of 493 pregnant women recruited through prenatal clinics in four US cities during 1999,2001. Sperm concentration, semen volume and motility were determined at the centres and morphology was assessed at a central laboratory. While between-centre differences in sperm morphology and sample volume were small, sperm concentration and motility were significantly reduced in Columbia, MO (MO) relative to men in New York, NY, Minneapolis, MN and Los Angeles, CA; total number of motile sperm was 113 × 106 in MO and 162, 201 and 196 × 106 in CA, MN and NY respectively. Differences among centres remained significant in multivariate models that controlled for abstinence time, semen analysis time, age, race, smoking, history of sexually transmitted disease and recent fever (all p -values <0.01). We hypothesized that poorer sperm concentration and motility in MO men relative to other centres might be related to agricultural pesticides that are commonly used in the mid-west. We investigated this hypothesis by conducting a nested case,control study within the MO cohort. We selected 25 men in this cohort for whom all semen parameters (concentration, % normal morphology and % motile) were low as cases and an equal number of men for whom all semen parameters were within normal limits as controls. We measured metabolites of eight non-persistent, current-use pesticides in urine samples the men had provided at the time of semen collection. Pesticide metabolite levels were elevated in cases compared with controls for the herbicides alachlor and atrazine, and for the insecticide diazinon (2-isopropoxy-4-methyl-pyrimidinol) (p -values for Wilcoxon rank test = 0.0007, 0.012, and 0.0004 for alachlor, atrazine and diazinon respectively). Men with higher levels of alachlor or diazinon were significantly more likely to be cases than men with low levels [odds ratios (OR) = 30.0, 16.7 for alachlor and diazinon respectively], as were men with atrazine over the limit of detection (OR = 11.3). These associations between current-use pesticides and reduced semen quality suggest that agricultural chemicals may have contributed to the reduced semen quality seen in fertile men from mid-Missouri. [source] Carotenoids/vitamin C and smoking-related bladder cancerINTERNATIONAL JOURNAL OF CANCER, Issue 3 2004J. Esteban Castelao Abstract Previous epidemiological studies of fruit and vegetable intake and bladder cancer risk have yielded inconsistent results, especially with respect to the role of cigarette smoking as a possible modifier of the diet-bladder cancer association. A population-based case-control study was conducted in nonAsians of Los Angeles, California, which included 1,592 bladder cancer patients and an equal number of neighborhood controls matched to the index cases by sex, date of birth (within 5 years) and race between January 1, 1987 and April 30, 1996. Information on smoking, medical and medication history, and intake frequencies of food groups rich in preformed nitrosamines, vitamins A and C and various carotenoids, were collected through in-person, structured interviews. Beginning in January 1992, all case patients and their matched control subjects were asked for a blood sample donation at the end of the in-person interviews for measurements of 3- and 4-aminobiphenyl (ABP) hemoglobin adducts, and glutathione S -transferases M1/T1/P1 (GSTM1/T1/P1) and N -acetyltransferase-1 (NAT1) genotypes. Seven hundred seventy-one (74%) case patients and 775 (79%) control subjects consented to the blood donation requests. In addition, all case patients and matched control subjects were asked to donate an overnight urine specimen following caffeine consumption for measurements of cytochrome P4501A2 (CYP1A2) and N -acetyltransferase-2 (NAT2) phenotypes. Urine specimens were collected from 724 (69%) case patients and 689 (70%) control subjects. After adjustment for nondietary risk factors including cigarette smoking, there were strong inverse associations between bladder cancer risk and intake of dark-green vegetables [p value for linear trend (p) = 0.01], yellow-orange vegetables (p = 0.01), citrus fruits/juices (p = 0.002) and tomato products (p = 0.03). In terms of nutrients, bladder cancer risk was inversely associated with intake of both total carotenoids (p = 0.004) and vitamin C (p = 0.02). There was a close correlation (r = 0.58, p = 0.0001) between intakes of total carotenoids and vitamin C in study subjects. When both nutrients were included in a multivariate logistic regression model, only total carotenoids exhibited a residual effect that was of borderline statistical significance (p = 0.07 and p = 0.40 for total carotenoids and vitamin C, respectively). Cigarette smoking was a strong modifier of the observed dietary effects; these protective effects were confined largely to ever smokers and were stronger in current than ex-smokers. Smokers showed a statistically significant or borderline statistically significant decrease in 3- and 4-aminobiphenyl (ABP)-hemoglobin adduct level with increasing intake of carotenoids (p = 0.04 and 0.05, respectively). The protective effect of carotenoids on bladder cancer seemed to be influenced by NAT1 genotype, NAT2 phenotype and CYP1A2 phenotype; the association was mainly confined to subjects possessing the putative NAT1 -rapid, NAT2-rapid and CYP1A2-rapid genotype/phenotype. The carotenoid-bladder cancer association was not affected by the GSTM1, GSTT1 and GSTP1 genotypes. © 2004 Wiley-Liss, Inc. [source] Spatial planning, mobilities and culture,Chinese and New Zealand student preferences for Californian travelINTERNATIONAL JOURNAL OF TOURISM RESEARCH, Issue 3 2007Chris Ryan Abstract Itineraries are under-researched within tourism, which is arguably strange given their potential importance as determinants of visitor expenditure distribution, and how itinerary planning may become a tool of destination management in determining which areas are most affected by visitor flows, whether positively or negatively. This exploratory study required students in New Zealand and the Peoples' Republic of China to draw maps of potential trips to the south-west of the USA in order to assess to what degree differences might exist as to (i) preferred places to visit; (ii) durations of stay; (iii) speeds of dispersion and concentration at the points of embarkation and disembarkation (in this instance Los Angeles); and (iv) total distances travelled. Differences were indeed found, and ethnicity appeared to be the main explanatory variable for the differences. Chinese students were found to travel slightly less, not to become so dispersed overall, but were also found to have higher rates of dispersion and slower rates of concentration at the commencement and at the end of the trip. The itineraries also suggest a further triangular pattern of travel that can be added to the categories identified by Oppermann. Copyright © 2007 John Wiley & Sons, Ltd. [source] Exploring multiple dimensions of race and violence in Los AngelesINTERNATIONAL JOURNAL OF URBAN AND REGIONAL RESEARCH, Issue 3 2007Jooyoung Lee First page of article [source] Immigrant Place Entrepreneurs in Los Angeles, 1970,99INTERNATIONAL JOURNAL OF URBAN AND REGIONAL RESEARCH, Issue 2 2002Ivan Light Proclamations of the death of Los Angeles' growth machine are premature. These proclamations overlook the growing role of immigrant Korean and Chinese entrepreneurs in regional property development. Since 1970, Korean and Chinese entrepreneurs have seriously restructured Los Angeles' morphology, creating hierarchically arranged residential and business clusters for co,ethnic immigrants. Koreatown and Monterey Park are the brand names most familiar to outsiders, but these prominent localities really coexist with a multiplicity of less well,known ethnic communities that owe their origins to immigrant property developers. The immigrant property developers use the classic methods of the growth machine: buy land cheaply, promote it in Chinese or Korean emigration basins, then sell it to co,ethnic immigrants at a profit. In the process, the immigrant property developers reduce the difficulty of immigration to Los Angeles at the same time that they enhance its perceived desirability. The success of the Chinese and Korean developers highlights the hazard of assuming, as is conventionally done, that ethnic residential clustering arises from leaderless social processes. In both these highlighted cases, entrepreneurial elites created residential clusters of co,ethnics from conscious, long,term plans that required political as well as economic savoir,faire. In so doing, the immigrant property developers joined the Los Angeles growth machine whose fortunes, admittedly, have been waning among the native born population of the region. La mort annoncée de la dynamique de croissance de Los Angeles est prématurée. Ce serait oublier le rôle grandissant des chefs d'entreprise immigrés coréens et chinois dans l'aménagement immobilier régional. Depuis 1970, ces entrepreneurs ont considérablement restructuré la morphologie de Los Angeles, créant des ,agglomérats' commerciaux et résidentiels hiérarchisés pour migrants de m?,me ethnie. Si Koreatown et Monterey Park sont des noms bien connus des étrangers, ces lieux dominants coexistent en réalité avec une multiplicité de communautés ethniques moins renommées qui doivent leurs origines à des promoteurs immigrés. Ces derniers appliquent les mécanismes classiques de la prospérité: acheter le terrain bon marché, le promouvoir dans des bassins d'émigration chinois ou coréens, puis le vendre à profità des immigrants co,ethniques. Ainsi, les promoteurs immigrés facilitent l'immigration vers Los Angeles tout en en accentuant l'aspect attractif. La réussite des aménageurs chinois et coréens souligne le risque qu'il y a à supposer, comme bien souvent, que tout regroupement résidentiel ethnique naît de processus sociaux non dirigés. Dans les deux cas exposés, les élites commerciales ont créé des regroupements résidentiels de m?,me ethnie selon des plans délibérés à long terme, impliquant un savoir,faire à la fois politique et économique. Ce faisant, les promoteurs immigrés ont rejoint la dynamique de croissance de Los Angeles qui, il est vrai, a vu décliner les succès au sein de sa population de souche. [source] Becoming American/Becoming New Yorkers: Immigrant Incorporation in a Majority Minority City,INTERNATIONAL MIGRATION REVIEW, Issue 4 2002Philip Kasinitz Many observers have noted that immigrants to the United States are highly concentrated in the largest metropolitan areas of a relatively few states. Though immigrants diffused into many places that had previously seen relatively few immigrants during the 1990s, as of the 2000 census, 77 percent of the nation's 31.1 million foreign born residents still lived in six states , California, New York, Texas, Florida, New Jersey, and Illinois. According to the 2000 census, the two largest metropolitan areas, Los Angeles and New York, accounted for one third of all immigrants (http://www.census.gov/Press-Release/www/2002/demoprofiles.html). While immigrants moved into many new areas during the 1990s, making the challenge of incorporating their children a national issue, their concentration in our largest cities remained pronounced. [source] Pilot Test of an Attribution Retraining Intervention to Raise Walking Levels in Sedentary Older AdultsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 11 2007Catherine A. Sarkisian MD OBJECTIVES: To pilot test a new behavioral intervention to increase walking in sedentary older adults. DESIGN: Pre,post community-based pilot study. SETTING: Three senior centers in greater Los Angeles. PARTICIPANTS: Forty-six sedentary adults aged 65 and older. INTERVENTION: At four weekly 1-hour group sessions held at the senior centers, a trained health educator applied a theoretically grounded, standardized "attribution retraining" curriculum developed by a multidisciplinary team of investigators. Participants were taught that becoming sedentary is not inevitable with aging and that older adults should attribute being sedentary to modifiable attributes rather than to old age. A 1-hour exercise class including strength, endurance, and flexibility training followed each weekly attribution retraining session. MEASUREMENTS: Change from baseline in steps per week recorded using a digital pedometer was measured after 7 weeks. Age expectations (measured using the Expectations Regarding Aging-38 survey, a previously tested instrument on which higher scores indicate that the participant expects high functioning with aging and lower scores indicate that the participant expects physical and mental decline) and health-related quality of life were measured using in-person interviews. RESULTS: Mean steps per week increased from 24,749 to 30,707, a 24% increase,equivalent to 2.5 miles (2-sided t -test P=.002). Age expectation scores increased 30% (P<.001), and the changes in age expectations and steps per week correlated (correlation coefficient=0.39, P=.01). Participants experienced improved mental health,related quality of life (P=.049) and reported less difficulty with activities of daily living (P=.04). More than 50% of participants reported improvements in pain, energy level, and sleep quality. CONCLUSION: In this small pre,post community-based pilot study, a structured attribution retraining curriculum accompanied by a weekly exercise class was associated with increased walking levels and improved quality of life in sedentary older adults. Attribution retraining deserves further investigation as a potential means of increasing physical activity in sedentary older adults.

Spencer Banzhaf This research illustrates how the methods developed for meta-analysis can serve to document and summarize voluminous information derived from repeated sensitivity analyses. Our application is to the sensitivity of welfare estimates derived from discrete choice models to assumptions about the choice set. These assumptions affect welfare estimates through both the estimated parameters of the model and, conditional on the parameters, the substitution among alternatives. In our specific application, the evaluation is in terms of estimated benefits of air quality improvements in Los Angeles based on discrete choices of neighborhood and housing.

[source] Exclusive use of acid citrate dextrose for anticoagulation during extracorporeal photopheresis in patients with contraindications to heparin: An effective protocol,JOURNAL OF CLINICAL APHERESIS, Issue 2 2008Elena Nedelcu Abstract Extracorporeal photopheresis (ECP) routinely uses heparin for anticoagulation. For patients with contraindications to heparin, alternative anticoagulation using acid citrate dextrose (ACD-A) has been reported to be safe and effective. However, detailed ECP protocols that exclusively use ACD-A anticoagulation and minimize citrate toxicity have not yet been published. We report a protocol that completely replaces heparin with ACD-A for ECP, which was developed at the University of California, Los Angeles (UCLA), and our experience since its implementation. ECP was performed with the UVAR XTS photopheresis system using ACD-A and control of the rate of citrate infusion. Calcium gluconate solution was administered prophylactically and as needed for symptoms of citrate toxicity. The medical records of patients who underwent ECP using the ACD-A protocol between January 2003 and July 2006 were reviewed. The incidence and severity of citrate toxicity and the technical data for all procedures were analyzed. During this period, 94 ECP procedures were performed with ACD-A anticoagulation on five patients. All patients tolerated the procedures well without significant complications. Only minimal symptoms of citrate toxicity (grade 1) were observed in 24.5% of all procedures; symptoms resolved promptly following administration of additional calcium gluconate. In conclusion, an effective protocol for ECP using ACD-A anticoagulation exclusively in patients with contraindications to heparin employs continuous monitoring of flow rates and prophylactic administration of calcium gluconate to minimize citrate toxicity.

[source] Usefulness of high-sensitivity IL-6 measurement for clinical characterization of patients with coronary artery diseaseJOURNAL OF CLINICAL LABORATORY ANALYSIS, Issue 3 2005Valter Lubrano Abstract Interleukin 6 (IL-6) may represent an early marker of inflammatory activation and may be useful to ameliorate risk stratification in patients with ischemic heart disease. The aim of this study was to verify the performance characteristics of an ultrasensitive immunoassay (Biosource International, Camarillo, CA) for high-sensitivity (hs)-IL-6 measurement in comparison with hs-R&D Systems (Abingdon, United Kingdom) and Immulite System (Diagnostic Products Corporation [DPC], Los Angeles, CA) methods in patients with ischemic heart disease. In addition, hs,C-reactive protein (hs-CRP) concentrations were measured, to evaluate the correlation with hs-IL-6 levels. We measured IL-6 and CRP serum levels in 39 patients with ischemic heart disease and in 12 controls. Out of the 39 patients studied, 13 were affected by unstable angina, 13 by post,acute myocardial infarction (AMI) unstable angina, and 13 by stable angina. The imprecision profile and functional sensitivity were performed measuring 9 different serum pools in 10 runs. The Biosource method had the best performance characteristics as compared to the others. Mean IL-6 level was higher in patients with unstable and post-AMI unstable angina with respect to controls. CRP levels were elevated in patients with post-AMI. In the whole population a high significant linear regression was observed between Biosource hs-IL-6 and hs-CRP serum levels. The Biosource method for IL-6 measurement is characterized by a high functional sensitivity that allows a better stratification of patients with ischemic heart disease. J. Clin. Lab.

[source] Expanding self-help group participation in culturally diverse urban areas: Media approaches to leveraging referent powerJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 4 2004Keith Humphreys Accumulating research attests to the benefits of self-help groups for people who have various chronic health problems. Expansion of self-help group participation may enable a broader portion of society to experience these health benefits. The Media and Education for Self-Help (MESH) Project was an effort to increase interest in health-related self-help groups among middle- and lower-income people in two California urban areas with minority,majority populations. A diverse coalition of self-help group leaders designed English- and Spanish-language radio public service announcements and posters that were disseminated in Oakland and Los Angeles. The outcome measures in each urban area were self-help-group-related telephone inquiries to local information and referral agencies (English and Spanish language) and the number of individuals attending self-help groups at agencies hosting many groups. Telephone caller data were also gathered in a nonintervention control urban area (Sacramento). Los Angeles experienced an overall increase in telephone calls about self-help groups during the MESH intervention, whereas the control urban area had no change in the number of telephone calls over the same period. The initial sharp increase in self-help-group-related telephone calls was not sustained in Oakland, however. The number of Spanish-language calls about self-help groups increased 821% in Los Angeles and 149% in Oakland in the period from the 6 months that preceded the project through the first 6 months of the MESH Project. In the MESH Project urban areas, the number of visits to self-help groups was significantly higher in intervention months than in the same calendar months of the preceding year, particularly in Oakland, where the increase exceeded 300 visits to self-help groups per month. These intriguing findings are discussed in terms of their health policy and program evaluation implications. © 2004 Wiley Periodicals, Inc. J Comm Psychol 32: 413,424, 2004. [source] Sexual Homicide: A Spatial Analysis of 25 Years of Deaths in Los AngelesJOURNAL OF FORENSIC SCIENCES, Issue 5 2007Isaac T. Van Patten Ph.D. Abstract: Although it has been frequently studied over the last 100 years, empirical studies of sexual homicide are lacking. The majority of the existing studies have been descriptive in nature. In this study, we consider the spatial geometry of sexual homicide and the impact of time and distance on case solvability. An analysis of sexual homicides (n = 197) from 1980 to 2004 for Los Angeles County was conducted. Offender and victim journey to encounter site, journey to body disposal site, and journey-after-crime trips were examined. Descriptive and bivariate analyses were performed to examine victim, offender and case characteristics. Using logistic regression models both time factors and offense geometries were found to be significant predictors in case solvability. Simpler geometries are significantly more likely to be solved than cases with complex geometries and the longer a case remains unsolved the less likely it is that it will be closed. The results provide support for some of the findings from earlier descriptive studies and extend our understanding of the spatial geometry of sexual homicide.

Por medio de observar la preparatión de tales casos, entrevistar a abogados y solicitantes, y asistir a audiencias en la corte federal de inmigración en Los Angeles, se analiza estas características. La investigatión se enfoca en los casos conocidos como "suspensión de deportatión". Para ganar, el solicitante tiene que haber vivido en los Estados Unidos por siete años, mostrar buen caracter moral y probar que deportation causarfa un dafio extremo al aplicante o a un pariente del aplicante. El anãlisis indica que, aunque no se menciona la raza ni la etnicidad del solicitante, las características preferidas se basan en la cultura anglosajóna, lo cual promueve un modelo anglosajón del cuidadano ideal. Por eso, aún cuando se ganan los casos, la ley impone requisitos que perjudican a ciertos sectores de la población. [source] | ||||||||||||||||||||||||||||||||||||||||||||||
